Our Bass MIDI system features a solid state contact system (Hall effect sensors & magnets) for the left hand side of your accordion.  Both the Bass notes and Chords become MIDI, and the connection socket will usually be on the bass panel of your accordion.  The standard output will be Bass on MIDI channel 3 and Chords on channel 2, if you have different needs please specify in the contact form below.
